# Are aluminium castings and fasteners covered by the UK CBAM?

Canonical: https://senseible.earth/answers/uk-cbam-aluminium-castings-fasteners-default

Yes. Heading 7616, other articles of aluminium, is on HMRC's UK CBAM list. Cast aluminium articles not covered elsewhere (7616 99 10) carry a default of 4.547 tCO2e per tonne, and aluminium nails, screws, bolts, nuts, rivets and washers (7616 10 00) 4.888. Iron castings under 7325 are not covered.

## Defaults

- 7616 99 10: cast articles of aluminium, not elsewhere specified: 4.547 tCO2e per tonne.
- 7616 10 00: aluminium nails, tacks, staples, screws, bolts, nuts, rivets, washers and similar: 4.888.
- Aluminium goods carry both carbon dioxide and perfluorocarbons in the UK scheme.

## The aluminium and iron difference

In chapter 73 only listed headings are covered, so cast iron articles under 7325 fall outside. In chapter 76, heading 7616 is listed, so aluminium castings that stay in 7616 are inside. Castings classified as machine or vehicle parts in chapters 84 or 87 are outside both.

## What your figure contains

- Ingot or scrap bought in, as a precursor: primary and secondary metal treated separately where known.
- Fuel for melting and holding furnaces, and heat treatment.
- Cutting, welding and finishing are outside the boundary; grid power is not counted until at least 2029.

## What Senseible does here

Senseible reads ingot and scrap purchases with melting and heat treatment fuel invoices, so your casting figure can be set against 4.547 before your buyer files. We build the figure from your records and check every figure in-house; for the UK it must then be verified by a verifier accredited for UK CBAM. Have your own verifier? Send it to them.
